MEANS FOR PREVENTING THE RAISING OF DUST BY MOTOR-VEHICLES.

Application filed April 6, 1916.

To allv whom it mag/.concern Beit known that we, BENJAMIN JONES, a subject of the King of Great Britain, and resident at 54 Gate street, Cwingors Road, Gwaun Cae Gurwen, Glamorganshire, lVales, and PHILLrr JOHN REEs, a subject of the King of Great Britain, and resident at post-ollice, Tairgw-aith, GwaunCae G-iiuwen aforesaid, have invented certain new and useful Improvements in Means for Preventing the Raising of Dust by Motor- Vehicles, of which the following is a specilication.

This invention relates to the prevention of dust raising by motor vehicles, and has for its object to provide means, which may be actuated by theniotor of the vehicle, and serve to prevent the raising of dust by the vehicle wheels.

As is .well known, the raising of dust by the wheels of a rapidly moving vehicle is largelyidue totheiinvard rush ol'iair to lill the partial vacuum created by the rapid forF ward movement of the wheel as a whole, the vacuum being greatest in the space immediately behind the point of contact between the tread of the wheel and the ground, with the result that the air which rushes in gathers up from the surface of the road, and becomes laden with, dust, which is thereafter carried upward by the vortex created by the rotation of the peripheral portion of the wheel in contact with the surroundi ng atmosphere.

The aim of the present invention is to nullify the tendency to create a partial vacuum behind the wheel, by the delivery ol a counter-current of air.

The invention will be more :tully described with reference to the accompanying drawings in which like characters indicate like parts in all the views and in which Figure 1 is a diagrammatic plan illustrating how the invention is applied to the wheels of a motor car, Fig. 2 is a side elevation illustrating the positions of the air-intake and delivery pipes relatively to a wheel, Figs. 3 and 4t are respectively a side elevation and a front elevation oit the end of an air-de livery pipe, shown on an enlarged scale, and Figs. 5 and 6 are respectively a front elevation and an end elevation of a fan casing.

L and V are the front wheels mounted on an axle c, and @Z and e are the rear wheels mounted on an axle f of a motor car of any well known construction which is not illus- Speccation of Letters Patent.

Serial No. 89,379.

trated. g is the casing of a fan 7i, said cas ing g being connected with the frame of the vehicle by means of hooks j, j formed in one with a strap L secured to said casing. The casing g has a duplex inlet pipe Int leading to the center oll one side thereof and connected with Vflexible pipes n, o which extend toward either side of the vehicle and are furnished with junction pieces y), y wl'iereof the junction piece 7) is connected with two flexible pipes i' and s leadingv to the front ot the wheels a. and (Z respectively, while the piece q is connected with two flexible pipes t and u leading to the front of the wheels Z) and c respectively.

The casingg hasan outlet pipe o connected by a flexible pipe i0 with a junction piece m, connected on the one hand by a flexible pipe y with-another junction piece a, which is connected with flexible pipes 11 and 12 leading to the rear of the wheels a and Z respectively, and connected on the other-hand with flexible pipes 13 and 14: leading to the rear of the wheels b and e respectively.

Each of the flexible pipes r, s, t, u, 11, 12, 13 and 14 terminates in a mouthpiece 15 (see especially Figs. 3 and fl), said mouthpieces being held adjacent to the peripheries of the corresponding wheels and close to the ground (see Fig. 2) by clamps 16 (Figs. 3 and 4t) and suitable stays (not shown). Each mouth-piece 15 is formed. with lateral wings ll' which are adapted to extend on either side oli the peripheral poi tion oit' the wheel as shown in `Fig.

The tan le, runs on suitable ball bearings and its spindle 18 supported at the inlet side et the :tan by a spider traine (not shown) and at the. other side or' the 'fan b v the strap /u which is oll'set as at lf) for this purpose, and said spindle has mounted thereon between said ol'lset part of the strap and the casing g a sprocket wheel 20 whereby the fan it may be driven through a sprocket chain (not shown) from any suitable rotating part of the motor, or, if desired, the fan may be driven by an independent source o'lf power such as an electric motor.

In use, the Yfan It draws .in air from 'the :front ot' the wheels a, o, Z and c through the pipes fr, a, t, u, n, o, m, and delivers air through the jiipes iv, y, 11, 12, 13 and 1l to the corresponding inoutlrpieces 15 whence the air issues at the peripheral portion oit the wheel, z'. e. adjacent to the tread and sides of the tire, as a counter-current to eddies there set up, so that the aising oi" dust by said eddies is prevented.

lt is not essential that the air drawn in by the fan It should be led trom in front oi? the Wheels a, Y), l and e, but this arrangenient is found preferable as reduction of air pressure at said parts assists the prevention of dust raising.

That we claini is 1. In means for preventing the raising of dust by the Wheels of a motor vehicle, the combination with a vehicle, of pipes having mouth pieces arraliged in i'ront and rear ol' the wheels adjacent the treads thereof and close to the ground7 and an air apparatus connected with the said pipes and drawing in the air in front of the wheels and delivering it to the rear oi' the wheels.

Means for preventing the raising of dust by the wheels ot motor vehicles, said means comprising the combination with a inotor vehicle of a fan casing mounted on said Vehicle, a fan in said casing, an air inlet to7 and an air outlet from said fan casing, pipes connecting said inlet With n'ioutli-pieces, said mouth-pieces being arranged in front ol the road wheels of the vehicle, and pipes connecting said outlet with mouth-pieces, said second-named mouthpieces being arranged in rear of the road wheels of the Vehicle, said first-named and said second-named mouth-pieces being disposed adjaeent the peripheries of the corre spending wheels and close to the ground.

El. Means for preventing the raising of dust by the wheels of niotor vehicles, said means comprising the combination with a motor vehicle of a fan easing mounted on said vehicle, a fan in said easing, means for driving said fan, an air inlet to, and an air outlet from, said :tan easing, junction pieces and flexible pipes connecting said inlet with inlet inoutlrpieces, and junction pieces and flexible pipes connecting said outlet with outlet mouth-pieces, said inlet mouthpieces being arranged in front of, and said outlet mouth-pieces being arranged in rear of, the road Wheels of the vehicle7 said inlet and outlet mouth-pieces being disposed adjacent the peripheries of the corresponding wheels and close to the ground and having lateral wings adapted to extend on either side of the peripheral portions of said wheels, substantially as set forth.
